Grace KSN/tbs United States Patent Oce 3,426,685 Patented Feb. 11, 1969 l Claim ABSTRACT F THE DISCLOSURE A mushrooming projectile comprising a jacketed lead filled bullet. The jacket has an internal rib pattern at the ogive portion of the projectile consisting of a series of annular ribs and longitudinal extending ribs intersecting some of the annular ribs This invention relates to projectiles for firearms, and more particularly an improved bullet.

It is therefore the main purpose of this invention to provide an improved bullet which is designed to be manufactured in two weights of jackets, a light one for regular arms and a heavy one for big game rearms.

Anot-her object of this invention is to provide an improved bullet which is designed to travel in a fiat trajectory, resist wind velocity, overcome brush deflection and maintain perfect accuracy.

Another object of this invention is to provide an improved bullet wherein the apparent density of lead is controled within the jacket of said bullet in such a manner that the arcuate portion thereof is adapted to receive an impact of considerable sheer force due to the mushrooming effect caused by lead substance within said jacket.

Still another object of this invention is to provide an improved bullet which is inexpensive to manufacture, easy to mass-produce, is of rugged construction, and provides maximum utility tothe hunter.

Other objects and advantages of this invention will become apparent from a consideration of the following detailed description taken in connection with the accompanying drawing wherein a satisfactory embodiment of the invention is shown.

In the drawing:

FIGURE 1 is a cross sectional lines 1-1 of FIGURE 2.

FIGURE 2 is a bottom plan view of this invention.

According to this invention, an improved bullet includes the bullet cover or jacket 11. The bottom portion 12 of jacket 11 is provided with a circular opening or hole 13 for pouring the lead substance therein. The main body portion of cover 11 is provided with a cylindrical body portion 16 which is integrally connected with an arcuate or ogive jacket portion terminating at apex 14. Within said ogive portion 15 a circular, laterally disposed rib 17 inwardly extends from the inside section of ogive portion 1S. A second circular lateral rib 19 is spaced parallel to the previously mentioned rib 17. A plurality of equally view taken along the spaced, arcuately positioned longitudinal ribs 18 are inwardly extending from ogive body portion 15 of the bullet iacket 1l. Said longitudinal ribs 18 are suitably spaced between the lateral ribs 17 and 19 in perpendicular relationship thereto. A third circular, laterally disposed rib 20 extends inwardly from jacket 11 at the approximate borderline between the cylindrical body portion 16 and the ogive body portion 15. Said third inner rib 20 is in parallel with second rib 19 and the area there between serves as a constricting means for preventing the mushrooming effect toward the cylindrically disposed main body 21 which, in this case, would outwardly expand its body portion 16 thereby releasing the lead core, as often happens in the bullets ofthe prior art.

It will also be noted, that, in operation, the mushrooming effect takes place in semiconical section 22 which is enclosed by ogive body or jacket portion 1S and operably supported by lateral ribs 17 and 19 and longitudinal ribs 18. Therefore, upon an impact, said mushrooming effect will be directed toward the conversion point of the nose cone or apex 14.

From the above description, it is thought that the construction and advantages of this invention will be readily apparent to those skille-d in the art.

What Inow claim is:

1. An improved bullet, comprising in combination, a bullet jacket including a cylindrical portion comprised of a cylindrical side wall and a circular rear end wall, said bullet jacket further including an ogive portion extending integrally frorn a forward end of said cylindrical portion, at least three laterally positioned circular ribs along a longitudinal axis of said jacket, vsaid ribs being concentric with said longitudinal axis and being in parallel spaced apart relationship to each other, a plurality of equally spaced substantially longitudinal ribs extending inwardly from said ogive portion of said bullet jacket between a rst and a second lateral said rib, a circular, central opening in said rear end wall of said jacket for admitting a quantity of lead into said jacket, said admitted lead forming a lead core within said jacket, said ogive portion between said first and second lateral ribs adapted to cause mushroom effect upon the the impact of said lead core within said jacket, said second and a third lateral rib constituting an area for protecting said lead core from the mushroom effect and thereby preventing the outward expansion of said jacket, said mushroom effect upon the impact of said lead core tending to concentrate in an area between said first lateral rib and a nose cone of said ogive portion.
